ABSTRACT:
A chain of reclosable plastic bags with the bags formed of a thin plastic material having front and rear walls with reclosable pressure interlocking rib and groove elements on the confronting faces at the lower end of the bag which will eventually form the bag top when the bag is disassociated from a chain with the bag walls being unattached along the upper end so that the bag is open and the bag may be filled by inserting contents between the edges with stiffening ribs on the surface of the bag material parallel to the unattached edges so that the bag wall and edge of the bag above the rib are prevented from collapsing with the bags interconnected to each other at the sides to form a chain.
